1. If AI is like other technologies, there will be job displacement and temporary upheaval after which new jobs will be created and prosperity increases - this is by far the only good way to increase prosperity

2. If AI is so good that it is a proper superset of humans and can do all jobs humans can do, this is a huge deal and we don’t even have the vocabulary to express what would happen

I don’t foresee a third option.

the fact no one can actually describe these "new jobs" makes #2 appear increasingly more probable.
